A short-run monopolistic competition equilibrium graph has the same properties of a monopoly equilibrium graph. Long-run equilibrium of the firm under monopolistic competition. The company still produces where marginal cost and marginal revenue are equal; however, the demand curve (MR and AR) has shifted as other companies entered the market ...
Different economists have different views about what events are the sources of market failure. Mainstream economic analysis widely accepts that a market failure (relative to Pareto efficiency) can occur for three main reasons: if the market is "monopolised" or a small group of businesses hold significant market power, if production of the good or service results in an externality (external ...

Hence, there are significant barriers to market entry, such as, patents, market size, control of some raw material. Examples of monopolies include public utilities (water, electricity) and Australia Post.
An example PPF: points B, C and D are all productively efficient, but an economy at A would not be, because D involves more production of both goods. Point X cannot be achieved. Productive efficiency occurs under competitive equilibrium at the minimum of average total cost for each good, such as the one shown here.

The monopolies can set the price above the marginal cost of the production. In this case, the allocation is not efficient. It results in the dead weight welfare loss to the society as a whole. In real life, the government's intervention policy to monopoly enterprises will affect the allocation efficiency.
